Hmm. I did find some web pages on using pcmanfm and some tweaks to hal or something to get icons on the desktop for removable media. However, some of the links were dead or confusing to me.
I also looked into using idesk, which would be perhaps the best choice. But these pages seem hard to find.
I did find what looks to be a very simple solution using rox. I think rox has much more flexibility than pcmanfm in managing icons, but it's not as easy to use in setting the wallpaper.
Ultimately, I think I'd like to use idesk + nitrogen if I can find the pages I need to setup idesk properly for removable media. In the meantime, I'll experiment with rox. Here's the link I'll try out:
